TUNING ATTACHMENT FOR WIND MUSICAL IN$TRUMENTS.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed February 20, 1918. Serial No. 218,343.

' State of Indiana, have invented certain new anduseful Improvements inTuning Attachments for IVind Musical Instruments, of which the followinis a specification.

This invention re ates to wind musical instruments particularly of thereed type and the object of the invention is to provide an improvedmeans whereby the air column may be lengthened or shortened for thepurpose of tuning.

While the invention is applicable to different forms of reedinstruments, itis particularly adapted asa mouthpiece adjustment forsaxophones.

I provide means whereby the instrument may be rendered flat or sharp bysimply manipulating a threaded collar or sleeve.

I have provided means whereby the mouth-' piece may have longitudinalmovement lm parted to it without any rotative movement with respect tothe main portion of the instrument. I have also provided means wherebythe attachment may be readily applied to existing instruments withoutunduly altering them.

In the"drawi11gs Figure 1 is afragmentary side elevational view of asaxophone to which my invention is applied;

Fig. 2 is a longitudinal sectional view through the tuning attachment,the parts being separated;

Fig. 3 is an end view of the instrument part, separated on the line 3-3of Fig. 2;

Fig. 4; is a sectional view on the line 4-4 of Fig. 2; Fig. 5 is afragmentary side elevational View of the tuning attachment; and

1 Fig. 6 is a longitudinal sectional view at right angles to the sectionshown in Fig. 2.

Referring now to the drawings, 1 designates the tubular end of aninstrument, for example saxophone to which my invention is applied, saidend being provided with external screw threads 2 and having in its endwall a plurality of guide receiving openings 4 and 5. 7 represents athin tube that serves as a' liner for the tubular end 1, and preferablyalso as a liner for the mouth-piece 6. The tube 17 carries an internallythreaded sleeve or collar '8 having knurled portions 9 and 10 andadapted for rotative movement on the tube 7 butheld against longitudinalmovement with respect thereto by the shoulder 11. A collar 16 havingthreaded engagement with sleeve 8 serves to hold the tube 7 in abuttingrelation with the sleeve 8. Collar 16 is retained in place by set screw17. The internally threaded portion of the sleeve o is spaced away fromthe tube 7 to provide an annular guide in which the instrument end 1 maytravel, and by which said end may be confined and guided while the tube7 is acting as a liner for said end. Within this space are thelongitudinally extendin uide pins .12 and 13 rigid with the should dr 11fixed on the tube 7 so that when said pins enter the openings 4. and 5the tube 7 will be held against rotative movement with respect to theend 1, and inasmuch as the mouthpiece 6 is carried by the tube 7rotative movement of the mouthpiece will be prevented. An internallysmooth flange 8 on the sleeve 8 receives the end I of the instrument andguides said end to receive the liner tube 7 Within its bore and the pinsl2, 13 Within its openings 4:, 5; and also directs the threads 2 to theannular confining space between the sleeve and liner tube. Ihe describedorganization of parts not only aifords a more substantialconstructionbut a more convenient assembly, since it is only necessaryto insert the threaded end of member I within the flange 8 and to turnthe mouth-piece and sleeve together until the pins l2, 13 seatthemselves, which will arrest the mouthpiece in proper position,whereupon contin ued turnin will be limited to the sleeve alone and. temouth-piece and tubular end,

while retaining proper relation to each other, may be given relativelongitudinal adjustment at will.

,The sleeve 8 is turned in the'direction of the initial S (Fig. 5) toshorten the air column and sharpen the tone of the instrumerit, and inthe direction of the initial F change of pitch may be accomplished withone hand of the player by simply turning the sleeve 8 in the properdirection. Being relatively thin, the liner tube 7 makes no dislidinstruments comprising a tubular instrument end, a liner tube having anaxially sliding hearing within said instrument end,

and a sleeve surrounding said liner tube but "separated therefrom andproviding therewith an annular space extending substantially the lengthof tuning adjustment and fitting the instrument end, said liner tube andsleeve being united beyond said annular space by a bearing that permitsturning but resists axial movement of the sleeve upon the liner tube,means being introduced between the sleeve and instrument end thattranslates a rotary movement of the one, into an axial'movement in theother, and connection being provided between the liner tube and theinstrument end which permits axial movement but resists rotation betweenthem.

2. A tuning. connection for two parts of a wind musical instrumentcomprising a liner tube adapted to carry the one and to slide axiallywithin the bore of the other of two instrument partsto be connected, andhaving a pin and openingengagement that prevents relative rotation onthe instrument art in which it slides, and a sleeve surrounding theliner tube but separated therefrom and forming therewith an annularspace adapted to fit the end of the instrument part in which the linertube slides, said sleeve having a feeding screw thread engagement withsaid last-named instrument part through which it develops relativesliding movement between the latter and the liner tube.

3. A tuning a wind musical instrument comprising a connection for twoparts ofliner tube adapted to carry the one and toslide axially withinthe bore of the other of two instrument parts to be connected, andhaving a pin and opening engagement that prevents relative rotation onthe instrument part in which it slides, and a sleeve sur-v rounding theliner tube but separated therefrom' and forming therewith an annularspace adapted to fit the end of the instrument part in which the linertube slides said sleeve having a feeding screw thread engagement withsaid last-named instrument part through which it develops relativesliding movement between the latter and the liner tube; said sleeve alsohaving a longitudinal extension that receives the end of said instrumentpart guides it to the feeding screw threads and positions the parts toinsure the pin and opening engagement in the assembly of the parts. a

4. In a tuning connectionfor the tubular parts of wind musicalinstruments, a liner tube having portions inserted within the bores oftwo parts to be connected, and having an axial sliding movement in oneof said parts, a sleeve having a shouldered bearing 'upon said linertube at a point intermediate its inserted portions and extending fromsaid bearing axially over the sliding inserted part of said liner tubebut separated therefrom and forming therewith an annular space thatreceives the instrument part in which the liner tube slides, meanscarried by the sleeve to develop. said sliding movement of the line tubein which it slides, and means carried by the liner tube to resistrotation of the instrument part that receives it.

The foregoing specification signed at Elkhart, Indiana, this 9th day ofNovember, 1917.
